This can happen for both the Magnify and the Rotate events independently.
As both events are summarized in one GDK_TOUCHPAD_PINCH event sequence, a
little state machine handles the case of two NSEventPhaseBegan events in
a sequence, e.g. Magnify(Began), Magnify(Changed)..., Rotate(Began)...
such that PINCH(STARTED), PINCH(UPDATE).... will not show a second
PINCH(STARTED) event.
